The satellite-observed nighttime light emission (NTLE) data provide a new method for scrutinizing the footprint of human settlements. Changing NTLEs can be attributed to the direct/indirect influences of highly complex factors that are beyond the ability of simple statistical models to distinguish. Besides, the relatively coarse resolution of the NTLE products combined with light from human settlements may produce misleading results, as the relationship between spatiotemporal heterogeneity in the growth of developed land (e.g., urban and rural residences, shopping centers, industrial parks, mining plants, and transportation facilities) and the associated NTLEs has not been adequately analyzed. In this study, we developed a total nighttime brightness index (TotalNTBI) to measure the NTLEs with the defense meteorological satellite program/operational linescan system (DMSP/OLS) nighttime light data enhanced by sharpening the edges of the pixels. Thirty-six key cities in China were selected to investigate the relationship between the total developed land area and the associated TotalNTBI from 2000 to 2013 using panel regression and a simplified structural equation model (SEM). The results show that the overall trend in TotalNTBI agreed well with that of the total developed land area (mean adjusted R2 = 0.799). The panel regression models explained approximately 71.8% of the variance of total developed land area and 92.4% of the variance in TotalNTBI. The SEM revealed both the direct and indirect influences of independent variables on the total developed land area and the associated TotalNTBI. This study may provide useful information for decision-makers and researchers engaged in sustainable land development, urban management, and regional developmental inequality, focusing on recent issues, such as retrospective analysis of human footprint with sharpened nighttime NTLE products, the loss of natural and semi-natural land due to the sprawling developed land area indicated by intensively lit area, and the low efficiency of land development indicated by the anomalies of developed land area and associated NTBIs.

This paper focuses on explaining how individuals set goals on multiple performance episodes, in the context of performance feedback comparing their performance on each episode with their respective goal. The proposed model was tested through a longitudinal study of 493 university students’ actual goals and performance on business school exams. Results of a structural equation model supported the proposed conceptual model in which self-efficacy and emotional reactions to feedback mediate the relationship between feedback and subsequent goals. In addition, as expected, participants’ standing on a dispositional measure of behavioral inhibition influenced the strength of their emotional reactions to negative feedback.

This study focused on college students’ attitudes toward the relationship between online civic responsibility and online civic engagement and its impacts. It also investigated the mediating roles of online civic learning and online civic expression in this relationship. A survey was conducted in Taiwan, testing for indirect effects with mediated variables using a structural equation model. The study tested hypotheses about the mediations of online civic learning and online civic expression on this relationship between online civic responsibility and online civic engagement for college students. The results indicate that the mediators of online civic learning and online civic expression fully mediate the relationship between online civic responsibility and online civic engagement.

This study examined the impact of E-CRM on customer loyalty with the mediating effect of customer satisfaction in the banking industry. Customer satisfaction is important for loyalty because when the customers are satisfied with the services offered by their service providers, the relationship gets stronger which further leads to positive word-of-mouth. The data was collected using purposive sampling from 836 banks’ customers who were using E-CRM services and the data was analyzed using structural equation model (SEM) through AMOS. The results revealed that E-CRM and customer satisfaction had a significant positive impact on customer loyalty and also customer satisfaction partially mediated the relationship between E-CRM and customer loyalty. This study would offer useful acumen to both academicians and marketers and would help the bank managers to improve the quality of the services provided to their customers.

During the new normal era after pandemic Covid-19, the tourism destination needs to struggle and adapt for recovery. This process requires optimal human resource performance. The objective of this study is to examine the model of human resource performance in tourism destination after pandemic. Leadership, motivation, and organizational commitment are consider as the antecedents of human resource performance. This study implements a quantitative approach. The data collection method used a questionnaire that distributed to 105 employees in Balkondes as respondent. The data analysis method used Structural Equation Model (SEM) with AMOS. The results show that leadership, motivation, and organizational commitment have a positive and significant effect on human resource performance. The results also show that organizational commitment has mediating effect on the relationship between leadership toward human resource performance, and motivation toward human resource performance.

AbstractThis study examines the effect of perceived organisational politics on organisational silence through the mediating role of organisational cynicism. In addition, it tests the effect of perceived support on this relationship. A quantitative (questionnaire survey) design was used to gather data from 346 employees in three public hospitals in Iraq. The structural equation model was used for data analysis. The results demonstrate that all the major hypotheses were accepted, and important role of perceived support in reversing the positive relationship between perceived organisational politics and organisational cynicism was also highlighted. Furthermore, the mediating role was clear in terms of organisational cynicism and the relationship between perceived organisational politics and organisational silence.

We examined the impacts of emotional intelligence and self-leadership on coping with stress, and assessing the mediating roles that positive affect and self-efficacy play in this process. Participants were 575 students at 2 Chinese universities, who completed measures of coping with stress, self-leadership, emotional intelligence, self-efficacy, and positive affect. The structural equation model analysis results indicated that self-efficacy fully mediated the relationship between emotional intelligence and active coping, as we had predicted. Further, self-leadership had a direct effect on active coping. However, positive affect and self-efficacy did not mediate the relationship between self-leadership and coping with stress. Implications are discussed in terms of theoretical contributions and interventions for coping with stress.
